Since being launched on the web in 1997, the number of conversations has exceeded 65 million. Unlike other chatterbots, Cleverbot’s responses are not programmed into it, but rather selected from phrases entered by humans in previous conversations. Humans type into the box below the Cleverbot logo and the system finds all of the keywords or an exact phrase matching the input and after searching through its saved conversations of previous chats, responds to the input by finding how a human responded to that input in past conversations when posed by Cleverbot,[2][3] although the commercial version of Cleverbot has more than one thousand requests per server, the ones hosted were for 1 or 2 people per server. This allowed more speed and quality of responses hosted by the artificial intelligence system.

I can tell you from experience, chatting with CleverBot can get a bit creepy at times. Some of the responses generated by CleverBot’s computer can seem so human-like.

PLEASE NOTE – Cleverbot learns from real people – things it says may seem inappropriate – use with discretion, and at YOUR OWN RISK

PARENTAL ADVICE – Visitors never talk to a human, however convincing it looks – the AI knows many topics – use ONLY WITH OVERSIGHT
